From c703beb31d8f95c1e861cb4007b02c3eaaf93c33 Mon Sep 17 00:00:00 2001 From: Richard Spiegel Date: Mon, 10 Sep 2018 13:42:00 -0700 Subject: mb/google/kahlee/variants/baseboard: Set STAPM percentage Default STAPM percentage causes a lot of thermal throttling on grunt. AMD experimented with 80%, it works for grunt. This is initial code to provide easy change path for other grunt based platforms. BUG=b:111608748 TEST=build and boot grunt.
